CVE-2025-21925 llc: do not use skb_get() before dev_queue_xmit()

In the Linux kernel, the following vulnerability has been resolved: llc: do not use skbget before devqueuexmit syzbot is able to crash hosts 1, using llc and devices not supporting IFFTXSKBSHARING. In this case, e1000 driver calls ethskbpad, while the skb is shared. Simply replace skbget by...

CVE-2025-21925

CVE-2025-21925 : In the Linux kernel, a vulnerability was fixed where skb_get() could be used before dev_queue_xmit() when a shared skb is processed (e.g., with IFF_TX_SKB_SHARING). The documented exploit path involves syzbot crashing a host via the llc_sap_action_send_test_c path, with the e1000...
